Assessing peculiarities of condition and behaviour of low-level bridges

Abstract

The article considers peculiarities of operation and monitoring of low-level bridges which are found on highways of regional, intermunicipal, and local significance. The vibrations of the bridge superstructure are considered in detail taking into account its interaction with other elements of the structure and the environment. It is proposed to use the natural frequency of vibration as a characteristic, the change of which takes into account the change in the condition of the bridge structure.
